Bluetooth doesnt work well with windows 7

Iv had some JBL on ear bluetooth wireless headphones for a while now, worked okay with windows 10, work perfect with tablet. Bought another computer a few weeks ago, has windows 7, having problems, firstly there is no real straight forward way of connecting (pairing) to the pc, its hit and miss and abit of luck, and when I do get connected all I hear is a popping noise with the backround sound coming through. Not sure if there is a fix to this, or if I should just buy some wired headphones.
